English writer Horace Walpole’s fantastical Strawberry Hill, a castle constructed in the outer London village of Twickenham in 1748 and worked on until Walpole’s death, in 1797, sparked the Gothic Revival movement and is a model of historic preservation today. To conceive it, Walpole mined various books on medieval architecture, and a series of architects, among them Robert Adam, were brought on throughout the years to interpret the details he’d determined to use.
